Question

2-butanone is converted into 3-methyl-3-hexanol using a grignard reagent prepared from 1-bromopropane and magnesium metal in thf solution. List the procedural steps required to collect the alcohol product by microdistillation.

Answer 1

Answer:

Here's what I get.

Explanation:

At the end of the reaction you will have a solution of the alcohol in THF.

The microdistillation procedure will vary, depending on the specific apparatus you are using, but here is a typical procedure.

• Transfer the solution to a conical vial.
• Add a boiling stone.
• Attach a Hickman head (shown below) and condenser.
• Place the assembly in in the appropriate hole of an aluminium block on top of a hotplate stirrer.
• Begin stirring and heating at a low level so the THF (bp 63 °C) can distill slowly.
• Use a Pasteur pipet to withdraw the THF as needed.
• When all the THF has been removed, raise the temperature of the Al block and distill the alcohol (bp 143 °C).
